营运船舶主机能效和碳排放等级评定方法

Rating and evaluation method of energy efficiency and carbon emission intensity of main propulsion diesel engines in operation ships

摘要

摘要:
目的为使营运船舶主推进柴油机（主机）具备可操作的能效和碳排放强度评定方法以及等级划分标准，
方法将单位营运燃油消耗率（SFOC）作为主机的能效指标，提出主机各级能效划分阈值的计算公式和能效等级偏离系数的计算方法，确定各级能效划分阈值的偏离系数，制定出能效等级评定的方法、划分范围及原则。以营运船舶“育鲲”轮的主机为应用对象，基于实验数据，对其进行能效等级评定。
结果计算结果表明，“育鲲”轮的主机营运燃油消耗率为190.03 g/（kW·h）；1，2级及2，3级能效划分阈值分别为191.86和203.15 g/（kW·h）。最终，将“育鲲”轮主机的能效等级评定为1级。
结论研究结果有效反映了“育鲲”轮主机的管理水平、技术状态、能效水平及碳排放状态，所提方法符合亚太能源中心等机构关于评定方法的目标性、合理性、可行性、系统性及导向性要求。

Abstract:
Objectives In order to establish a practical evaluation method and rating standard for energy efficiency and carbon emission intensity of main propulsion diesel engine(main engine) in operation ships,
Methods this paper uses the Specific Fuel Oil Consumption(SFOC) of main engine as the energy efficiency indicator, provides formulas for calculating the threshold of main engine energy efficiency at various level and the methods for calculating the energy efficiency level deviation coefficient, by which the level deviation coefficients of the energy efficiency level thresholds are determined, and the method, scope and principle of the energy efficiency evaluation are established. Moreover, the proposed methods are then applied to evaluate the energy efficiency of YUKUN ship based on the experiment data.
Results The calculation results reveals that the main engine's SFOC is 190.03 g/(kW·h), the thresholds of main engine energy efficiency for the 1st and 2nd grade is 191.86 g/(kW·h), and the 2nd and 3rd grade 203.15 g/(kW·h). The energy efficiency of YUKUN ship is then classified as the 1st grade.
Conclusions The results can effectively reflect the management level, technical status, energy efficiency level, and carbon emission status of YUKUN ship. The methods are in line with the requirements of the Asia-Pacific Energy Centre and other agencies in terms of objectivity, rationality, feasibility, systematism and guidance.
